Re: HELP!!!!!!! How do you reprogram the idle (rbhanlon)
Do you want to change the idle RPM or just have the computer relearn its idle?
If its the latter just disconnect the batter for a few hours, let everything go
dead, reconnect it. Start it. Let it idle for 5 - 10 minutes. Drive it for a solid 50 miles without turning off the car.
Changing the idle point you would need something like LS1 edit.

Re: HELP!!!!!!! How do you reprogram the idle (redcorvette1995)
Someone else once posteed the following detailed procedure:
From the 2001 Service Manual:
Idle Learn Procedure
The learned idle procedure needs to be done if any of the following events occur:[list][*]The powertrain control module (PCM) is disconnected[*]The battery is disconnected[*]The PCM loses power[*]The PCM is reprogrammed
The engine idle is unstable when the learned idle position is lost.
Automatic Transmission
Perform the following procedure in order to return the learned idle to the correct position:[*]Turn OFF the ignition.[*]Restore the PCM battery feed.[*]Turn OFF the A/C controls.[*]Set the parking brake, and block the drive wheels.[*]Start the engine.[*]Ensure that the engine coolant temperature is more than 80°C (176°F).[*]Shift the transmission into Drive.[*]Allow the engine to idle for 5 minutes.[*]Shift the transmission into Park.[*]Allow the engine to idle for 5 minutes.[*]Turn OFF the engine for 30 seconds.
Manual Transmission
Perform the following procedure in order to return the learned idle to the correct position:[*]Turn OFF the ignition.[*]Restore the PCM battery feed.[*]Turn OFF the A/C controls.[*]Set the parking brake, and block the drive wheels.[*]Place the transmission in Neutral.[*]Start the engine.[*]Ensure that the engine coolant temperature is more than 80°C (176°F).[*]Allow the engine to idle for 5 minutes.[*]Turn OFF the engine for 30 seconds.

Re: HELP!!!!!!! How do you reprogram the idle (yellow01)
To raise the idle, you need to reprogram the computer, by LS1 edit, Powerloader. Superchips or etc.

Re: HELP!!!!!!! How do you reprogram the idle (rbhanlon)
1- TURN KEY ON BUT DO NOT START
2-OPEN FUSE BOX COVER UNDER HOOD REMOVE FUSE 16 & 23 [10 AMP]
3- YOUR DIC WILL NOW DISPLAY "check"messages for abs,ect.
4-turn igintion to off position
5-re -install fuses
6- start engine
7- allow engine coolant to reach 176 degrees f and run at this temp for at least 5 min.
8-shut down engine
9-let it rest 30 sec.
10-restart engine check for codes [there should be none]
11- drive car for at least 30 miles ,varying the speed. pcm will now relearn and adjust to new air flow and temp. at intake
you must follow these procedure exactly or you will have to start all over. :cheers:

Where do you get LS1edit?
